The RS Razor Xtreme Wheel is the world's most advanced Pinewood Derby Car Racing Wheel to date. With features like perforated wheels that are extremely light weight, the Patent-Pending Anti-Friction Inner Strip, A-Cad engineered design for perfect balance and machined from Delrin on a CNC for exacting tolerance, the Derby-Worx Pro RS Wheel is ready to run. Just add your choice of lubricant. Derby Worx has created a needle axle version of the highly popular RS wheel for even greater speeds. Less Surface Contact per Rotation equals greater speeds. The regular outlaw wheels have a linear contact between the wheel bore and the axle per revolution of .289 inches. Due to the smaller bore size, these needle wheels have a linear contact of 0.126 inches, a 56% reduction in surface contact per revolution. Over the course of a 32 foot track (actual distance traveled is about 27 feet); this results in a reduction of over 44 inches of linear contact ! Now that is FAST!!! Check your local rules to see what wheels are permitted.
